• Suggestions: 1. Practice daily. Do not wait until the night before the spelling test to cram for the test!2. Practice dividing the words into groups for each digraph to make it easier to memorize

the correct spelling.

IRREGULAR PLURAL WORDS

• Many nouns do NOT follow the regular pattern for adding -s or –es to show more than one (plural form).• Regular: hat + s = hats; watch + es = watches

• When words do not follow the regular pattern, we say they are IRREGULAR (ir = not).

“F” CHANGES TO “VES”

• Most of the time, when we have a SINGULAR noun ending with the letter “f” or “f + silent e” and we change it to a PLURAL noun, we change the “f” to “ves.”
